Balancing mechanics and metabolism: Elevational variation in the microanatomy of hummingbird flight muscle

The Anatomical Record, EarlyView.
Abstract Factors varying along elevational gradients impose strong aerodynamic and physiological constraints on powered flight, yet the internal microanatomical variation associated with elevational context in animals under such conditions remains poorly understood.

Morphophysiological dynamics of the proximal post‐testicular ducts in Crotalus durissus Linnaeus, 1758 (Squamata: Viperidae)

The Anatomical Record, EarlyView.
Abstract The organization and function of reptilian excurrent ducts remain poorly characterized, particularly in Neotropical snakes. We provide the first integrative morphological, histochemical, immunohistochemical, and ultrastructural analysis of the proximal post‐testicular ducts of Crotalus durissus across reproductive stages.

Comparative analysis of cytoarchitectonic and neurochemical aspects of the globus pallidus in the rock cavy (Kerodon rupestris) and the common marmoset (Callithrix jacchus)

The Anatomical Record, EarlyView.
Abstract The globus pallidus (GP), a subcortical structure within the basal ganglia, plays a crucial role in modulating cortico‐subcortical circuits related to motor control and associative/limbic functions. However, the cytoarchitectonic and neurochemical organization of this structure remains poorly characterized in naturally existing wild‐type ...

Duck Orbivirus and Egg Production: A Newly Identified Duck Orbivirus Is the Etiological Agent of Egg Production Decline in Chinese Breeder Ducks

Animal Research and One Health, EarlyView.
Field samples from breeder duck farms with egg‐production decline were subjected to viral detection, genome sequencing, and virus isolation. Experimental infection demonstrated that duck orbivirus (DORV) causes a significant and persistent reduction in egg production in breeder ducks.

Extraintestinal Reprogramming of Colon‐Derived CD4+ Intraepithelial Lymphocytes Reveals a Mechanism Underlying the Gut–Joint Axis

Arthritis &Rheumatology, EarlyView.
Objective The gut–joint axis is a central paradigm in spondyloarthritis, yet the cellular mechanisms linking intestinal and joint immunity remain poorly understood. One potential link is T cell receptor αβ+ CD4+ colon intraepithelial lymphocytes (cIELs) that can traffic to extraintestinal tissues, including the joint.

From anthelmintic to neuro‐oncology: A systematic review of mebendazole repurposing for brain tumour therapy

British Journal of Clinical Pharmacology, EarlyView.
Abstract Aim Mebendazole (MBZ), a benzimidazole anthelmintic with established clinical use, has emerged as a repurposing candidate for primary brain tumours due to its multimodal anticancer actions and central nervous system penetrance. This systematic review synthesizes preclinical and clinical evidence evaluating MBZ's efficacy, mechanisms of action ...
